iollcnring description. A pair of diametrically opposed ears l-llproject from the adjacent end of the sleeve 18. and these ears are ofsubstantially the same width as the projeotioru; 30. A pin 252 extendstrz'insversely through each of the cars 31. and has journaled upoi'ieachof its ends a link that may he held against removal from the pin byhaving the end of the pin upset or riveted, A pin 3-4; is supported byand between the 'free ends of the links 33, and journaled upon, said pinis an antifriction riiiller 35. y y

L so -on pair of links 36 are pivoted upon the ends of the pin 34, andbetween the opposite ends of these,- is 'ionrnaleda roller-375' upon apin 38. It will'hle observed from Figs. 1 and 2, that the rollers 37occupy an ai'inular "oore 40 that is formed within the inner surface ofthe reduced end of the casing 1.5. u'

Two or more of these clutch actuatmechanisms comprising the aforesaidri'illi-n's and links, may he ein 'il'oyed, the nums her requireddepending somewhat upon the size and power ofthe clutch. UIl'i any case,they should be located at equal distances a oa'rt'i, and for convenienceI have shown two in eeni'ieetion with the embodiment herein ill l inted,and have located them diametriealijy' oppositt-a'ench other A. groom 4-1surrounds the exposed part of sleeve 18, leaving between said groove andthe :uljaeent end of said sleeve an annu- 'lar ridge 42 whereon theusual 3011211243 is mount l, said collar having trunnions 4A forcooperation of the shifting apparatus, iiulieated conventionally at 45'.The sleeve 18 may he prt'ividedwith anydesirecl number of holes 46, oneof said holes being shown in Figs. 1 and 2. A port 417 extendslongitlildinally thL'OIIglI the wall of the sleeve 18, fI'OIIl i innerend to the hole 40. for a purpose which will be described farther along.

A screw 49 isused to close an openin 50 that extends througl'ithereduced end thecasing adjacent the aperture through which. the sleeve18 reci n'oeates. When it is desired to fill the clutch'casing with oil,the screws 49 and 26 are removed, and oil is poured through the holevacated by the screw 26, until. it overflows through the hole 50, itheii'ig understood that the parts are turned in the position shown in.Figs; 1 and 2, during this operation. Thereafter the screws may be "rei)laced to retain the oil within the casing. I i i An inside}.)e.rip'heral flange 51 surrounds the aperture ofthereduced end of thecasing 15 and formse gutter which arreststtheflow of oil down along thesurface of the casing toward the sleeve18, the oilflowing fromthehighest point of thegutter down hoth sides of the clutch until it isdeposited in the jlmver portion of the casing.

By reason of the fact that the links 36assume an angle perpendicular' to the opposed surfaces wherewith theirrollers engage when the clutch is in effective actually locked orblocked against separation; in other words the well known condition,commonly ref center position, prevails; It is also clear from theforegoing that the centrifugal action of the clutch,.when it is inoperation, tends to hold these parts in effective position. a

In Fig. 5 I have illustrated a method of connecting the casing 15 to thehead 10, which I employ in connection with clutches that are so large asto render the screw thread connection of the former modificationimpracticable. In this instance, the head is provided with a lurality ofholes through which screws 55 reely" pass. These screws are threadedinto holes tapped into the end.

of the casing, and their heads 56 are countersunk within recesses in thehead- 10.

- Having thus described my invention, what I claim is: I 1. Thecombination with a driving and a driven element, of inner -uter conicalclutch members non-rotatable with respect to one, element,-a conicalclutch member in- 'termedia'te the former clutch members andnon-rotatable with respect to the other element, saidintermedi'ate c'utch member being provided with a hub within its inclined face, theinner conical clutch member being slidable on said hub and means formovin said clutch members toward and from eac other.

2. The combination of a cylindrical casing'having a clutch face at oneend and an abutment at the other end, a shiftable clutch' member withinsaid casing and non rotatable. with respect thereto, an intermediateclutch member between said clutch face and member and adapted to begripped thereby, an abutment member adjustably seand position, theclutch members are erred to as deadcured to said shiftable clutch memberand shiftable therewith within the casing, and means between saidabutments to move the same toward and from each other.

3. The combination with a driving and a driven element, of a pair ofclutch members non-rotatable with respect to one element, a clutchmember intermediate the former clutch members and non-rotatable withrespect to the other element, an abutmentv carried by each of theaforesaid pair of clutch members, said abutments being opposed to eachother and inversely arranged as compared to the arrangement of theclutch faces of said members,wherefore a separation of the abutmentswill cause the clutch members to be moved relatively toward each other,one of said abutments having a recess that opens toward the otherabutment, means bearing within said recess and that is adapted to bewedged between the opposed abutments, and mechanism for actuating saidmeans.
